If you can only get 89 dB or so, I would stick with amp power >30 w/ch.
Also, if you are going with a bookshelves, it might be better to go with one with very little bass. Trying to get any decent bass out of speakers tend to make them difficult to drive for SET amp.
I would pretty much rule out B&W for low powered SET. EPOS and ProAc would be a better brand to go with mid-powered SET. (10-20w/ch) SET compatible speakers are not that common in my area as well. I ended up just with going by other people recommendatation and purchased over the net.
